Yoga for Dummies

Cooking for Dummies is a good idea. What's the worst thing that can happen? You burn yourself on the stove, ruin a few pots and pans, and send a few people home hungry after your dinner party. Same with Computers for Dummies. The worst thing I can see happening there is some minor electrocution and a broken computer. But Yoga for Dummies... is that really a good idea? I see major potential for serious personal injury - especially if you really are a dummy.
